===Disassembling a hydraulic lifter=== {{Note1}}Before beginning work, have a clean well lit work area prepared. Use clean lint free rags or paper towels. To clean, use carb spray, acetone, lacquer thinner, or WD-40. To disassemble a lifter, depress the lifter cup using a wooden dowel or a pushrod. This allows the retainer clip to be easily removed from the groove in the lifter body. Use a pick and lift one side out of the groove and the clip will come out.<br> {{!}}Be careful to not accidentally shoot the clip across the shop. Once the clip is out, the pushrod cup and metering disc can be removed, followed by the inner plunger assembly. The plunger can be stubborn, tapping the open end against a cloth-covered wood block will usually bring the plunger to the top of the body allowing it to be coaxed out the rest of the way. [[File:Check details.jpg|thumb|300px|left|Check ball, spring and retainer cup in order]] On the bottom of the plunger you will see a cup and a stiff spring. Remove the spring and set it aside. Inside the cup is a small spring and check ball (left). Some designs use a small disc instead of a ball, however check "ball" will be used herein. The cup is a press-fit onto the plunger, it snaps off and back on. With a lifter that has collapsed or is noisy, often all that has happened is the cup assembly isn't fully seated into the recess on the bottom of the plunger, or a speck of dirt has lodged between the check ball and seat. Remove the cup using a pick and see that the tiny spring isn't bent, kinked or missing, and that the check ball is there and is smooth and shiny, and that the seat on the plunger that the ball seals doesn't have any ridges, burrs, or imperfections that would prevent the ball from seating properly. <br style="clear:both"/> ;Return to [[Lifters#Roller lifter|Roller lifter]].
